An original terroir
The uniqueness of the terroir of Saint Laurent Medoc lies in its diversity.
It is a patchwork: sandy-gravelly soil in the far west, becoming silica-gravel, silica-clay and clayey-limestone towards the west and the centre. To the east, on the gravelly slopes where the best vineyards are located, including La Tour Carnet, the soil is mainly composed of gravel dating from the Gunzian period and is very similar to that of the neighbouring appellations of Pauillac and Saint-Julien.
Facing south/southwest, many of the hillsides with clayey limestone subsoil are covered in a thick layer of Garonne and Pyrenees gravel.
It is on these large gravelly hills that you find the best vineyards. The 1855 classification testified to this by singling out Chateau La Tour Carnet.


The estate of Château La Tour Carnet
In the western part of the domain lies a ridge of starfish limestone, whose slopes are covered with clay from the Sannoisian period. This is known as the "Butte de La Tour Carnet", a geological curiosity that still leaves experts in wonder.
The eastern part stretches across hillsides facing south / southwest and comprises a gravelly hill typical of the Great Wines of the Medoc. The clayey limestone subsoil is covered in a thick layer of Garonne and Pyrenees gravel.
The final part located in the north consists of a wide plateau of fine gravel.
Years of painstaking experimentation have allowed us to get the very best from these soils by planting them with the most suitable varieties: the Butte is a soil for Merlots, while the hills are best suited for Cabernets.
